Abstract: Abstract of the Disclosure The specification discloses a semiconductor absolute pressure transducer assembly having a silicon diaphragm assembly and a covering member.  The silicon diaphragm assembly has a circular pressure sensitive diaphragm, on one surface of which is diffused piezoresistors and conducting paths.  The covering member composed of boro-silicate glass has a circular well formed therein.  A passivating layer of silicon dioxide is deposited on the surface of the silicon diaphragm assembly on which the piezoresistors and the conducting paths are diffused. Further, a conductive layer is formed on the passivating layer by, for example, evaporating silicon. The glass covering member is bonded on the silicon diaphragm assembly by Anordic Bonding, i.e., the silicon diaphragm assembly and the glass covering member are brought into contact and heated to a certain high temperature and a relative high voltage is applied across the conductive layer of the silicon diaphragm assembly and the glass covering member.  In this way the transducer assembly can be fabricated by employing Anordic Bonding without the usual disadvantages usually attendant upon this technique.

Abstract: ABSTRACT OF THE DISCLOSURE An expansion joint seal for use in roadways, bridges and the like adopted for use with a pair of elongated, parallel spaced-apart edge members defining a gap therebetween and each of the edge members having a generally C-shaped cavity opening towards said gap.  me seal includes mounting beads on each of its longitudinal edges for reception within the aforesaid edge member cavities and a double walled, resilient web construction spanning the aforesaid gap and being attached to the mounting beads.  The double walls of the web are disposed in an upper and lower relative relationship to one another and are connected to the mounting beads at correspondingly upper and lower portions thereon.  The upper and lower web walls fold downwardly upon movement of the edge members towards one another and corres-ponding reduction in width of the gap.  The upper and lower walls are connected to one another by a pair of downwardly ex-tending struts which cause the upper and lower walls to fold in a desired manner while also providing additional strength to the configuration.  The upper wall is surmounted by an inverted, V-shaped crown which folds upwardly away from the downwardly folding upper wall upon compression of the seal.  The upwardly folding crown portion thereby functions to eject incompressibles out of the gap and/or to preclude the disposition of incom-pressibles in the gap.

Abstract: A B S T R A C T      An underground storage reservoir for LNG or other fluids at cryogenic temperatures comprises an under-ground cavern       usually insulated, in which the cryogenic fluid is stored, an inner circulation system surrounding the cavern and comprising a plurality of passages       in or adjacent the cavern wall or in the ground immediately surrounding the wall, and an outer circulation system comprising a plurality of ducts    surrounding and spaced from the inner circulation system.  During operation of the reservoir to store a cryogenic fluid, a heat exchange gas is circulated through the passages of the inner circulation system so that the tempera-ture of the cavern wall and the ground immediately surrounding the wall is maintained within a pre-determined temperature range higher than the temperature of the stored fluid and the critical temperature at which the ground cracks.  A heat exchange gas is also circulated through the ducts of the outer circulation system so that a frozen zone is established and maintained in the ground spaced from and encircling the cavern and the inner circulation system.  This frozen zone halts the otherwise continuous drainage of water into the reservoir area from the surrounding ground both during construction of the cavern and the inner circulation system and during subsequent operation of the reservoir.  In addition, the temperature gradient established by the inner and outer circula-tion systems substantially reduces the rate at which water vapour would migrate through the ground in the reservoir area towards the storage cavern. The invention then involves adjusting the pressures in the inner and outer circulation systems, and perhaps also in the cavern itself, so that gas is caused to diffuse outwards through the ground towards the outer circulation system in counterflow to water vapour migrating inwards, so that the movement of water vapour is halted or reversed.
